Test		Result	Action
1	Check cable and terminal integrity: - Engine ECM pin B18 - Engine ECM pin B23 - Engine ECM pin B30	OK	Disconnect sensor and proceed to test 2
Faulty	Rectify fault, proceed to test 5
2	Check cable for short circuit: - Engine ECM pin B18 to ground - Engine ECM pin B30 to ground	OK	Proceed to test 3
Short circuit	Locate and rectify wiring fault, proceed to test 5
3	Check cable continuity: - Engine ECM pin B18 to sensor pin 3 - Engine ECM pin B23 to sensor pin 4 - Engine ECM pin B30 to sensor pin 1	OK	Proceed to test 4
Open circuit	Locate and rectify wiring fault, proceed to test 5
4	Check cable for short circuit: - Engine ECM pin B30 to Engine ECM pin B18 - Engine ECM pin B30 to Engine ECM pin B23 - Engine ECM pin B30 to Engine ECM pin A08 - Engine ECM pin B30 to Engine ECM pin A21	OK	Renew gear position sensor and contact pin and proceed to test 5
Short circuit	Locate and rectify wiring fault, proceed to test 5
5	Reconnect harness, clear fault code and run engine.	OK	Action complete - quit test
Fault still present	Contact Triumph service
